It make me wonder how creative they are turning those stuff into something that are really usefull. At same time I googled and found out the same story had been reported by AFP(Nov 2007). that “People could be infected with AIDS, (genital) warts or other diseases if they hold the rubber bands or strings in their mouths while waving their hair into plaits or buns.” and had been sold as cheap as 50 fen (USD 0.03) for a bag of ten.
So boys and girls, you better watch out!
